Century Drill & Tool hex key insert bit for driving 9/64" hex-socket (Allen) fasteners. Made from premium S2 steel for a long tool life while driving common or mild steel screws or case hardened screws, and rated by Century to last 2X longer than standard screwdriving bits.

• Hex size: 9/64"
• Overall length: 1"
• Premium S2 steel for long tool life in common, mild steel and case hardened screws
• Lasts 2X longer than standard screwdriving bits (manufacturer rating)
• Sold individually - manufacturer part 68459

Tip: Seat the bit fully in the fastener and keep the driver square to the screw axis - a hex bit held at an angle bears on the corners of the socket and will round it out. Century also offers these sizes together as a 9-piece hex key bit and holder set.
